Abstract

Bekannte Fahrradbremsen weisen eine Vorrichtung zur Beeinflussung der Übertragungskraft auf, die eine Schraubenfeder beinhaltet. Diese Schraubenfeder wird bei Überschreiten einer bestimmten auf den Handbremshebel aufgebrachten Betätigungskraft zusammengedrückt. Dabei ist es aber dann so, dass aufgrund der progressiven Federsteifigkeitskennlinie von Schraubfedern die auf die Bremse übertragene Übertragungskraft bei zunehmender Erhöhung der Betätigungskraft am Bremshebel progressiv zunimmt. Dadurch ist eine sichere und kontrollierte Dosierung der Bremskraft an dem gebremsten Rad nicht möglich.Known bicycle brakes have a device for influencing the transmission force that includes a coil spring. This coil spring is used when a certain value is exceeded Handbrake lever applied operating force compressed. there But then it is because of the progressive spring stiffness characteristic of helical springs the transmission force transmitted to the brake as the actuating force on the brake lever increases progressively increases. This is a safe and controlled dosage the braking force on the braked wheel is not possible.

Erfindungsgemäß ist eine Steuervorrichtung (10) mit der degressiven Kraftübertragungskennlinie vorgesehen. Dadurch wird erreicht, dass bei zunehmender Erhöhung der Betätigungskraft am Bremshebel (3) gleichzeitig die auf die Bremse (15) übertragene Übertragungskraft und somit die auf das zu bremsende Rad einwirkende Bremskraft abnimmt. Somit ist eine kontrollierte Dosierung der Bremskraft möglich, da bei zunehmender Betätigungskraft die Bremskraft abnimmt.

Figure 00000001
According to the invention, a control device (10) with the degressive power transmission characteristic is provided. It is thereby achieved that, as the actuating force on the brake lever (3) increases, the transmission force transmitted to the brake (15) and thus the braking force acting on the wheel to be braked also decrease. Controlled dosing of the braking force is thus possible, since the braking force decreases as the actuating force increases.
